pg_last_notice

(PHP 4 >= 4.0.6, PHP 5)

pg_last_notice Returns the last notice message from PostgreSQL server

Descrierea

string pg_last_notice ( resource $connection )

pg_last_notice() returns the last notice message from the PostgreSQL server on the specified connection. The PostgreSQL server sends notice messages in several cases, for instance when creating a SERIAL column in a table.

With pg_last_notice(), you can avoid issuing useless queries by checking whether or not the notice is related to your transaction.

Notice message tracking can be set to optional by setting 1 for pgsql.ignore_notice in php.ini.

Notice message logging can be set to optional by setting 0 for pgsql.log_notice in php.ini. Unless pgsql.ignore_notice is set to 0, notice message cannot be logged.

Parametri

connection

PostgreSQL database connection resource.

Valorile întoarse

A string containing the last notice on the given connection, or FALSE on error.

Exemple

Example #1 pg_last_notice() example

  $pgsql_conn 
pg_connect("dbname=mark host=localhost");

$notice pg_last_notice($pgsql_conn);
  
  echo 
$notice;
?>

Exemplul de mai sus va afișa:

CREATE TABLE will create implicit sequence "test_id_seq" for "serial" column "test.id"
